Moisture sensitivity varies by polymer and formulation. Dry only when product guidance or observed symptoms justify it, and use the spool maker's limits.
Do not use one universal schedule
Prusa's table assigns different temperatures and times to different Prusament products and warns that excess temperature can soften filament and make it stick together. That table is evidence for those products, not every brand.
Safer workflow
- Read the spool and manufacturer technical data.
- Confirm that the spool tolerates the proposed temperature.
- Use a dryer that can hold that temperature accurately.
- Record material, product, time, temperature, and result.
- Stop if the spool deforms or filament softens.
Dry storage with desiccant can reduce repeated drying. Prioritize highly hygroscopic materials, while accounting for local humidity and packaging.
